OK i had buddy build me a box, cause it turns out i'm handicapped. It's been a solid box, but i've come to decide it's fairly peaky, if i move the xover a tiny bit one way or another i shouldn't notice a huge huge difference should i?

Well i totally do, and it doesn't seem to hit a lotta notes, sometime i'm gonna try and put together a test tone cd of various tones to see what exactly it does play and how much before it drops off.

What makes a box peaky like this?

If it's ported, try to lengthen the port.

Also measure inside port length,
port diameter and let us know what thickness the wood is.

First thing your shop is an F'ing mess get your crap together and......lol just kidding

Try stuffing the ports/blocking them to esentially seal the box. If you find that the box now plays better it's probably incorrectly tuned (as in port length).

Not to familiar to Alpine gear but are they speced for use in a ported box ?
